gpio: omap: Fix interrupt names
When viewing the /proc/interrupts, there is no information about which
GPIO bank a specific gpio interrupt is hooked on to. This is more than a
bit irritating as such information can esily be provided back to the
user and at times, can be crucial for debug.
So, instead of displaying something like:
31: 0 0 GPIO 0 palmas
32: 0 0 GPIO 27 mmc0
Display the following with appropriate device name:
31: 0 0 4ae10000.gpio 0 palmas
32: 0 0 4805d000.gpio 27 mmc0
This requires that we create irq_chip instance specific for each GPIO
bank which is trivial to achieve.
